To all whom it may concern:

Be it known that I, HARRY J. DENAULT, a citizen of the United States of America, and a resident of Springfield, in the county of Ha'mpden and State of Massachusetts, have invented a new and useful Radio Receiving Plate, of which the following is a specification. I 4

My invention relates to improvements in the wireless or radio art, and more espeei ally to improvements in the receivin branch of such art, and consists essentia y of a radimreceiv-ing plate made up of a bed of insulating material, which bed by proton once is provided with a flange or rim that projects some distance above the top there of, and an electrically-conducting member mounted on said bed, and provided with means for having connected therewith an electrical conductor-pr wire, the plate thus constructed being of a size sufficient to receive thereon the base of the stand of a tele phone desk-set, together with such other parts and members as may be necessary or desirable in order to render the plate complete and serviceable in every respect, all as hereinafter set forth.

The primary object of my inventioiristo provide means for utilizing telephone desk- Sets, with their electric circuits, in place of either outside or inside serials, in connection with wireless-receiving outfits, such means consisting of a comparatively inexpensive, simple, convenient, strong; and durable radioreceiving plate.

Another object is toproduce such a plate which is adapted to receive thereon the base of the stand of a telephone desk-set, and to hold the same safely and securely in place.

A further object is to provide a. plate, of the character described above, which is on tirely safe to use, and does not in any way interfere with the ordinary operation of the telephone or injure the same.

l l/ ith this plate no aerial is required. other than that furnished by the telephone wires leading to the desk-set stand which is placed on said plate.

Other objects and advantages will appear in the course of the following description,

I attain the objects and secure the advantages of my invention by the means illustrated in the accompanying drawings, in which Figure '1' is a top view of a radio-receiving plate which embodies a-practical form and or my invention; 'Fig. a transverse see tron through said. plate, taken on lines 2-2,

looking in the direction of the associated arrow, in Fig. l, and, Fig. 3,,a side elevation of the plate its. a desk telephone-set or the stand thereo mounted on the plate, a ortion of the plate bein broken away to s ow the felt covering on t e bottom and edge of the base or said stand.

Similar reference characters desi ate similar parts throughout the several views.

some other shape, 'ience I do not desire to be restricted in this particuiar.

one desk-set is round, so far as the As illustrated in the drawings, the radio- "8' receiving plate comprises a bed 1 having a flange or rim 3 that extends above the top of said bed and clear around the same, a member 4: mounted on said bed insideof said rim, and having a. lug or arm 5 which extends outwardly through said rim beyond sand bed. lhe bed It with its rim 3 is made oi insulating material and preferably of vwood, while the member 4c is made of electrically-conducting material and preferably of copper. Theinember e may besecured to the bed 1 by means of a plurality of screws 6 which pass down through said member into sand bed. The rim 3 extends above the member t, and the space within said rim is largepuough to receive the base I7 L L "P 7 gas 6) oi the stand (as 8) of a telephone ssh-set.

A binding-post 9 is mounted on and secured to the urine 5, and a wire 10 is secured 9 1 to said bindiiig-post. \The wire 10 leads from a radio-receiving set (not shown), and would, the absence of this plate, be connected with either an outside or inside aerial, where it is now connected with said 0 plate,

The bottom of the base "I of the stand- 8 is covered with a piece of felt 1,1 which extends upwardl 7 around the edge of said base, but this iet frequently becomes worn to such an extent that the metal of said base is exposed. I provide, therefore, a felt mat 12 to place over the conducting member 4 in the event the metal on the bottom or bot- The mat 12 is not necessary and will not ordinarily be used when the felt on the bot tom edge of the base 7 becomes exposed.

tom of the base of the telephone stand is intact. Should the metal of the base 7 come into contact with the conducting n'len'iber 4-, a short circuit would be produc-zal and the telephone would be put outof operation, a though the operation of the wireless-re c1, ing set. would not be interfered with.

The rim -3 assists materially in preventing the stand 8 from being pushed otl" ot' the plate, but such-rim n'nrst be of insulating material, inasn'iush as that part of the base 7 which. is above the felt I] may and frequently does come -into contact with said rim, and then a short r-ircuit would result it the rim were of metal.

At 13 and 14 are represented the telephone Wires which are connected with the stand 8.

in practice, it is simply necessary to attach the wire from the radio-receiving set to the bindinwpost 9, and place the base 7 of the stand 8 llat on the conducting member l, the mat l2 being interposed il' necessary. The radio-receiving set is now ready for use in the usual manner, and it. is found that the operation of the same is materially enhanced by the use, with the aid or through the medium of my plate, of the telephone and telephone circuit in place of the aerial heretofore generally considered to be essential and necessary.

More or less change in the shape, size, construction and a'rrmugement of some or all of the parts 01* this plate, in addition to tlfii fi hereinbefore speeitically pointed out, may be made witl'iout departing from the nature of my invention orexceeding the scope of'what is claimed. I

Vt hat 1 claim my inventionjaTd de sire to secure by Letters Patent, is-

i. As an improved article of manufacture,

a radio-receiving plate comprising an insulatingunemher provided with an insulating rim, a conducting member mounted on said insulating member, said rim extending above said conducting member, and the latter being adapted to have connected therewith a radio-receiving set conductor, and to have placed thereon within said rim a tele phone desk-set stand, and means entirely to insulate said stand from said conducting member.

2. As an improved article of manufacture, a rmlio-reeeiving plate comprising an insulating member provided withan upwardlycxtending rim, a conducting member mounted on said insulating nirn'iber, and provided with an arm which extends through said rim beyond said insulating 'mei'n'ber for the purpose othaving connected therewith a radio-receivine set conductor, said conducting member being adapted to have placed thereon within said rim a tlelel'ihone deskset stand, and n'icans entirely to insulate said stand from said conducting mel'nbcr.

3'. AS an improved article of manufacture, a radio-receiving plate comprisingan insulating member provided with a rim, a conducting member mounted on said insudating member, said rim extending above said conducting, member, and the latter being adapted to have connected therewith a adio-reeeiving set; conductor, and to have placed thereon within said rim a telephone desk-set stand, and an insulating mat receivable on said insulating member within said rim, said stand being entirely insulated by said rim and mat from said conducting member.
